Description
Technical field
The utility model relates to generator, is specially diesel locomotive high speed alternating-current brushless excitation auxiliary generator.
Background technology
The hybrid powertrain system that domestic traditional diesel locomotive accessory drive system is made up of machinery, hydraulic pressure and DC Transmission, the advantage of this hybrid powertrain system is: the system applies technology maturation, cost is relatively low; Mechanical loss is big, efficient is low, the hydraulic power partial fault is many but also exist, the locomotive difficulty in arrangement, and locomotive efficiency is low, and the system maintenance amount is big, and energy resource consumption is many, and is less economical, the not high many shortcomings of reliability.For improving the locomotive utilization ratio, adapt to Chinese Railway great-leap-forward development requirement, the beeliner auxiliary system adopts and exchanges auxiliary system is technology trends.Exchanging auxiliary system employing brushless exciter is the technical development trend of the times.Therefore brushless exciter just becomes the critical component of auxiliary system.Need finish multi-states such as starting diesel engine, frequency reducing generating diesel engine low speed owing to run on the brushless exciter of diesel locomotive auxiliary system, particularly generator need have higher rotation speed, rotating speed is up to 3000r/min, work in simultaneously on the locomotive of operation, therefore its performance and structure are all had specific (special) requirements, the partial structurtes of existing brushless exciter can't meet the demands.Main generator rotor as existing brushless exciter adopts salient-pole structure, is difficult to bear for a long time the centrifugal force under the high rotating speed; Rotor needs to carry out rotor balancing by specific balancing frame, has taken space etc.
Summary of the invention
The utility model is for realizing the interchangeization and the non-brushing of diesel locomotive auxiliary system, can't satisfy the problem that beeliner exchanges the auxiliary system service requirement in order to solve civilian brushless exciter simultaneously, a kind of diesel locomotive high speed alternating-current brushless excitation auxiliary generator is provided.This generator is used for diesel locomotive and exchanges auxiliary system, and its structure is more complete, ripe, novel, attractive in appearance.Operational reliability is higher, can move continuously for a long time and not maintenance.
The utility model is to adopt following technical scheme to realize: diesel locomotive high speed alternating-current brushless excitation auxiliary generator, comprise the main generator that constitutes by stator and rotor, be positioned at main generator by being fixed in the stator on the main generator end cap and being fixed in the exciter that the rotor on the main generator rotor axle constitutes, be fixed on the main generator rotor axle rectifier that its input, output line terminal are connected with the main generator rotor coil with the exciter rotor coil respectively; The rotor of main generator adopts the non-salient pole structure, and the end is provided with the rotor field spider on the armature spindle that is fixed in main generator before and after the main generator rotor iron core, and the end winding of the rotor non-salient pole coil windings of main generator and rotor field spider binding are fixing.The three-phase synchronous generator of the diffusing embedding winding of general civilian non-salient pole, the end does not have support before and after the rotor core, and it is fixing that end winding does not only have the binding of latitude band with high strength, end winding is too bad, be unfavorable for ventilating, integrated not strong yet, be unfavorable for bearing the centrifugal force under the high rotating speed.The utility model makes end winding obtain shaping by rotor field spider and end winding and rotor field spider binding is fixing is set, integrated intensity height, and be beneficial to ventilation, and also improved the ability of bearing centrifugal force, improved the operational reliability of generator.
The utility model is fixed with balance weight on rotor field spider, be used for carrying out rotor balancing.Can cancel balancing frame of the prior art like this, save the space, make generator Structure novelty, compactness.
The utility model exciter is the salient pole pivot-rotatable type, and the magnetic pole and the yoke of stator are integrated, and is processed by monoblock steel plate integral body.Changed the connected mode that existing laminted pole is fixed on yoke.
The improvement of diesel locomotive high speed alternating-current brushless excitation auxiliary generator described in the utility model by partial structurtes, perfect, structure is more complete, ripe, novel.Make the overall construction design of motor more compact, thereby reduce the reliability that centrifugal acceleration is protected each element.This electric generator structure is reasonable in design, the efficient height, and temperature rise is low, and failure rate is low, and is safe and reliable, for generating interchangeization, the non-brushing of diesel locomotives in China auxiliary system are laid a good foundation.
Adopt no-brush synchronous generator because of fricton-tight contact portion, safeguard simply the reliability height, can move continuously for a long time and not maintenance, current-carrying part because of contacting without spin can not produce spark, is fit to have the operation occasion under the severe environmental conditions such as inflammable gas and many dust.Along with diesel locomotive exchanges the transmission auxiliary system with its transmission efficiency height, saving fuel oil, reliability advantages of higher, more and more generally acknowledged and extensive use that by everybody this generator will be brought into play its due effect for the locomotive auxiliary system exchanges transmission with its serial motors.
